Peregrine’s Next-Generation Phase-Locked Loop Device
Peregrine Semiconductor (San Diego, CA) announced from booth #1811 at the International Microwave Symposium in Seattle it has further expanded its high-frequency product line with the Integer-N PE33241 Phase-Locked Loop (PLL). The UltraCMOS technology-based PLL features a very low phase noise Figure of Merit (FOM) of -230 dBc/Hz, which improves the signal-to-noise ratio, thereby helping to reduce the overall system cost while improving performance. The device supports operation at 5 GHz with a 10/11 prescaler modulus, making it ideal for industrial transceivers, specialized transceivers, and clock generators requiring low phase noise. The PE33241 PLL is ideal for RF frequency generation; L, S and C-band synthesizers; and clock recovery in communication systems, mobile terminals, telemetry, radar, and portable radios. Features include:
- Low phase noise FOM (-230 dB/Hz) reduces interference, improves link quality.
- Selectable prescaler modulus of 5/6 or 10/11 provides design flexibility and minimizes unwanted frequency spurs.
- Supports operation at 5 GHz with the 10/11 prescaler modulus, and 4 GHz with the 5/6 prescaler modulus.
- Integrated phase detector and flexible serial or direct hard-wire interfaces.
- Low power consumption (80 mA at 2.8V) reduces thermal issues and extends battery life.
